ALBERT E. U nERwooD, or BEMIDJI, AND ARTHUR D, MoWERs, or

' SOLWAK'MINNESOTA Be itknown that we, ALBERT E. UNDER- wooD, residing at Bemidji, and ARTHUR I).

' cleaner, and Fig. 5 is a detail showing the MowERs, residing at Solway, in the county of Beltrami and State of Minnesota, citizens of the United States, have invented new and useful Means for Cleaning Plow-Colters, of which the following is a specification. I

Our invention relates to means for cleaning plowcolters, and has for its object. the prevention of the collection of debris upon the plow when used in brush-land, stubble-fields,

and other similar places where the work of plowing is'impeded by the presence of vegetable growth. b In such situations the rolling colter will not operate satisfactorily, and in the absence of some means for clearing litter away from in front of the plow it is frequently necessary to stop plowing to remove constantly-accumulating piles of litter or to employ an additional laborer for the purpose of removing such accumulations, which obstruct the movement of the plow.

In the accompanying drawings, forming part of this specification, Figure 1 is a pers ective view of a plow with our improved 0 eaner attached. Fig. 2 is a perspective view of the opposite side of the low and cleaner. Fig. 3 is a detail showing t e means for manipulating the cleaner. Fig. 4 is a detail showing the blade and shank of the shank of the cleaner with the means for journaling and adjusting the same on the beam of the low.

In t e drawings, 1 is a plow, to which is attached a colter 2, both'of ordinary construction. The blade 3 of the cleaner is riveted or attached by other suitable means to the shank 4. This shank is constructed withan offset 5, adapted to pass under the beam of the plow, and a vertical shaft 6,. adapted to be journaled' upon the plow-beam. The

shank is also provided with an arm 7, herein after more fully described. The shaft 6 is 'ournaled in the bracket or boX 8, which is olted or otherwise suitably attached to the plow-beam. Rigidly attached to the top of the shaft is a lever-arm 9, to which is, connected a rod 10 and a spiral tension-spring 11. The opposite end of the spring from that connected with the lever-arm isfixed to the plow-beam near its forward end by means of an eyebolt 12. The rear end of the rod 10 MEANS FORCLEANING PLOW-OOLTERS;

.is slidably supported upon or near the plowhandles by suitable meansas, for example, a clip 13 upon thercross-bar of the handlesand atits rear end the rod 10 is providedwith a suitable grip 14. The height of the blade 53 from the ground may be adjusted by means of a set-screw 15 inthe bracket 8, said screw being adapted to engage either of the grooves 16 in the shaft 6. The upper end 17 of the arm 7 is adapted in normal position to lie close to the plow-beam on the side 0 posite from that on which the cleaner-b ade is placed, and this arm thus tends to hold brush and other debris away from the plow-beam,'

and when the cleaner is operated, as herein after described, to clear the plow on that side from such debris.

ea e-1.1

In normal position the cleaner-blade 3 is held substantially parallel with the colter and moldboard of the plow by the action of the spring 11, and by the same means the end 17 of the arm 7 isheld adjacent to the plow-beam. Whenever brush or other debris accumulates in front of the colter in sufficient quantities to obstruct the working of the plow, the rod 10 is drawn toward the plowman by means of the grip 14, and

this movement of the rod turns the lever against the action of the spring 11 and throws the blade 3 outward into a osition substantially at right angles to the co ter and moldboard, thus thrusting the accumulation of brush away from the furrow, while the same movement swings the arm 7 outward on the opposite side of the plow and-thrusts back any rush which may have been pressed upward toward the beam on that side. When the grip 14 is released, the tension of the spring 11 returns the blade 3 and arm 7 to normal position.

Having described our invention, what we claim as new, and desire to protect by Let ters Patent, is

1. In a device of the class described, the

combination with a plow having a beam of a cleaner journaled upon the beam andprovided with a lever-arm, a spring and rod respectively adapted to hold the cleaner in a positi on substantially parallel with. the plowcam and to turn it at an angle with said beam, b'oth'said spring and rod bein connected with said lever-arm and plowearn. 2. In a device of the class described,the combination with a plow of a colter cleaner comprising a blade, a shaft journaled on the plow-beam and adapted to support said lade, a s ring adapted to hold the blade substantially parallel with the plowshare, and means for revolving the shaft and turning the blade.

3. A device of the class described, comprising a blade attached to a shaft, said shaft being provided with alever-arm to which is connected a spring and draw-rod adapted to turn the blade, all mounted upon a plow, for the pur oses specified. 4. A evice of the class described, comprising a plow, a shank adapted to be journaled upon the plow and provided with a cleaningblade and guard-arm and means for holding the blade and arm in normal position and for swinging them outward upon opposite sides of the plow.

5. In a device of the class described, the combination with a plow of a colter-cleaner j ournaled upon the plow-beam and provided with a lever-arm, a spring attached to the arm and adapted to hold the cleaner in normal position, and a rod, also attached to said 25 arm and adapted to turn the cleaner in its journal-bearing.

6. A device of the class described, comprising a plow, a shaft adapted to be journaled upon the plow and provided with a cleaning- 30 b ade, means attached to the forward end of the plow-beam for holding the blade in normal position and means for turning it outward therefrom.

In testimony whereof we have signed our 3 5 names to this specification in the presence of two subscribing witnesses.
